Takeaways

• 😀 The review focuses on the En Cubik Cobra S1 3D printer, which has generated significant interest following the release of a first-look video on the channel.
• 😀 The reviewer conducted a first-layer test using a 25x25 cm square at 0.2 mm layer height, with good results, though one corner showed slight imperfections.
• 😀 The printer was accompanied by a Bluetooth speaker kit as a gift, which needed to be assembled by the user, highlighting that the printer is still in pre-sale stages.
• 😀 The reviewer tested a custom-designed Sterling engine model on the printer, though a part broke due to using old filament and low extrusion temperature, which affected print strength.
• 😀 The first layer on the Sterling engine model came out well, showing the printer’s capability in handling detailed prints, with only minor issues visible on thin columns in the model.
• 😀 The printer performs well in terms of detail, especially on hanging elements like pipes, with results comparable to higher-end Core XY printers tested previously.
• 😀 The printer includes an intelligent AI system that detects printing issues like filament tangles or misprints and automatically pauses the print to allow for corrections.
• 😀 The reviewer confirmed that the printer's new design addresses the issues of the Cobra 3 model, particularly regarding bed leveling and warping, with the S1 model showing improvements.
• 😀 There is a new filament hub design on the Cobra S1, which requires longer filament retraction during color changes, but has slots to prevent filament tangling during this process.
• 😀 The reviewer shared some common user concerns regarding the Cobra S1, particularly around first-layer issues and software bugs, noting that these may be addressed with future firmware updates.
• 😀 The printer's pre-sale price is lower than its expected retail price, which may rise over time, and the reviewer encourages buyers to consider purchasing early if they are confident in the product's performance.

Q & A

What was the main reason for creating this video update about the Cubik Cobra S1 printer?

The video update was created because of the significant amount of questions and comments received after the initial review of the Cubik Cobra S1 printer. The creator wanted to address the most important questions and expand on their first impressions of the printer.

How did the first layer print test go on the Cubik Cobra S1 printer?

The first layer test was performed by printing a flat 25x25 cm square with a 0.2 mm layer height. The result was mostly successful, with only a small issue in one corner where the adhesion wasn't perfect. Overall, the first layer printed well with minor imperfections.

What was the special gift included with the printer, and how did it perform?

Along with the printer, the user received a Bluetooth speaker that could be printed and assembled by the user. Although the files for the speaker were not available from the manufacturer, the user found files from another user and printed the speaker, which turned out well and even featured RGB lighting. The speaker worked as expected, but it was an alternate project not directly from the manufacturer.

Was there any issue with the test model, a fictional Stirling engine, during printing?

Yes, during printing, the test model (a fictional Stirling engine) broke in one part. The issue was not due to the printer, but because the filament used was old and had been stored for a couple of years. Additionally, the printing temperature was lowered to avoid stringing, which affected the model's strength, leading to the breakage.

How did the print quality compare to other printers tested, like the CoreXY models?

The Cubik Cobra S1 printer performed very well compared to other CoreXY printers like the K1, FlashForge, and Q1 Pro, particularly in printing small, hanging details such as pipes. The print quality was considered to be excellent, with a smooth finish and no visible issues except for some minor imperfections on thin vertical supports.

How accurate was the first layer on the test model printed with the Cubik Cobra S1?

The first layer on the test model was flawless. Despite initial concerns about the first layer quality, the model printed without any issues, confirming that the printer could achieve high-quality first layers.

What was the user's experience with the intelligent AI features of the Cubik Cobra S1 printer?

The intelligent AI features, including automatic print error detection, were tested by intentionally disrupting a print by tilting a cylinder. The printer's AI successfully paused the print when it detected the issue and resumed it once fixed. This feature worked well, providing reassurance about the printer's ability to handle printing errors autonomously.

Were there any issues with the Cubik Cobra 3 model, and how does the S1 version compare?

There were reported issues with the Cubik Cobra 3, such as problems with the bed leveling system and a tendency for the bed to warp. The Cubik Cobra S1, however, seems to have resolved these issues with a new, sturdier bed construction. The S1 model shows promise in avoiding the flaws of its predecessor.

What are the differences between the Cobra S1's filament handling and the Cobra 3's system?

The Cobra S1 has a different filament handling system, with the filament hub placed at the back of the printer, requiring the filament to be fed through a longer PTFE tube to the extruder. This system increases the distance the filament must travel during color changes, which can cause issues if the filament gets tangled. The Cobra 3's filament hub is closer to the extruder, making the filament change process more efficient.

What was the user's opinion on purchasing the printer during the presale period?

The user acknowledged that buying the printer during the presale period carries some risks, as the printer was still being fine-tuned, with certain software bugs and minor issues. However, they considered it a good deal given the discounted price, and believed that the printer would perform well after further updates to the software and firmware.
